A nonlinear specification of demand for cash in Colombia
نویسندگان
چکیده
A nonlinear smooth transition regression (STR) model of the demand for narrow money in Colombia is specified using monthly data for cash, prices, the scale variable (industrial GDP), the interest rate and the rate of depreciation, within the single equation framework allowed by the data. In comparison with the linear error correction model, the nonlinear specification is highly superior according to the statistics. The dynamics described by this model matches both the magnitudes and the behavior of the aggregate demand for cash in Colombia during the sample period (1982.2-1998.11).

In a structural time series regression model, binary variables have been used to quantify qualitative or categorical quantitative events such as politic and economic structural breaks, regions, age groups and etc. The use of the binary dummy variables is not reasonable because the effect of an event decreases (increases) gradually over time not at once. The simple and basic idea in this paper i...
